hub problem

[D3R3K]

i have the switch on the fly 4X4 and my auto locking bubs do not work, but i can still lock the hubs in and get 4X4, i've seen that there are o-rings on the hub, or is the actual hub goig bad?

I know my 01 has the vacccum operated lock in hubs,,,, I put in Warn manuals. I wonder if your vac is whacked or a line is kinked/broken,came unconnected ? Does your Vac pump run more than normal?

Probably a vacuum leak, the wheel seal leaking or a hose off. Seems from what I've read that if you want 100% reliability then you have to go to warn manual hubs and give up the SOF idea. My wheel seals are shot and when I turn the switch my AC goes into defrost mode, a sure sign of a vacuum leak somewhere.

if they work when u lock them you have a vac leak like 99% of us it seems....could be a split line, could be a bad vac pump
check lines going to hubs in fenders and check line that hangs down in passanger footwell up into behind glove box for any obvious disconnections, or split or broken lines..

Simple fix. Take under $200, get yourself a set of Warn manual hubs, take the stock vac-craps off and throw in garbage, install Warn hubs. End of problem.

Or replace stopped up fitting at wheel and Save $200. There are several threads going on 4wd problems. Read all of them. Lots of info.

If your vac pump is not continously running, yer probably fine. I am still setup the same too. I did replace the vac seals in my hubs when I change out the hub assemblies due to bearing failure. I believe that if your seal is intact and the hoses are all ok, should not be a problem.

I will take mine off as close to the pump possible and capp them off later. No need to have a vac line down there if not needed, brush /sticks and junk could pull one of them off while muckking around.,
